GOSHEN, N.Y. (CBSNewYork) – Health officials in Orange County have issued a measles advisory after a case of the highly contagious infection was confirmed.

A resident contracted measles but it’s not clear where or when the person was infected.

Anyone with a rash and fever should call a medical provider before visiting an emergency room.

Symptoms usually appear within 12 days of exposure.

Those who have received two doses of the Measles, Mumps, and Rubella (MMR) vaccine are not at risk of contracting the illness, according to the county’s health department.

Those sickened with measles have flu-like symptoms with a rising flu. Eyes may become red and sensitive to light and small bluish-white dots surrounded by a reddish area may appear on a patient’s gums and on the inside of their cheeks.
